To all whom it may concern:

Be it known that I, HENRY- at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Im rovements in Upholsterers Buttons, of w oh the following 1s a specification,

reference being had therein to the accompanying drawlng.

which shall allow the free passage and circuy lation of air through-the cushion.

Another object is to provide an upholster-' ers button and piercing-pin adapted to be used in connection therewith. I accomplish the objects of the invention in the manner illustrated in the accompanying drawings, wherein similar letters'of referonce refer to and indicate like parts throughout the several views. The invention consists in the matters heremafter set forth and more particularly pointed out in the a pended clalms.

In the drawings igure 1 is a longitudinal central sectional view of the parts composing my new button, the several parts being somewhat separated along the1r axial km for convenience of illustration; Fig. 2 is a similar view the parts of the head in assembled condition orrelation; Fig. 3' is a sectional view of the button rovided with a piercing tool seated in the ower end of the. tubular shank, and Fig. 4 is a sectional view of a completed cushion provided with my new buttons.

In carryin outmy invention I employ a hollow tubu ar or cylindrical shank A of suitable shape and size and formed of sheet metal. The shankis provided at one end with an annular flang e'a, of one or a'plurahty of p'1eces and a cap-seat B formed usually of a metallic dlsk'ls provided with a central erforation adapted to pass over the shan so thatthe cap-seat may be brought against ghe lower face of the flange. a as shown in shape of a sk corresponding in general contour with the disk is adapted to be seated L.

The ca When the buttons are used to connect the cover material m with the backing material of the cushion, the heads are seated in the usual button-holders of a suitable rn ldboard (not shown) with their tubular shanks projecting u pin is seater in the free end of each shank as shown in Fi 3. This pin is composed of a solid cylindrical body (1, a tapered or pointed pin (1 'and an intermediate flange (1 the body bein ameter of the tubular shank and adapted to seat therein with the flange d resting on the free end thereof, as shown in Fig. 3.
